, The invention relates to a heating apparatus,

and more especially to a water heating apparatus vvfor heating buildings or the like.

The primary object of the invention is the provision' of an apparatus of this character, wherein a water circulating system is heated from a furnace and the latter is utilized'not only for the heating of the water but also for production of steam, being energy for an engine which drives a draft element and a water circulator, the apparatus'being usable both for heating and cooling service.

Another object of the invention is the provision `of an apparatus of this character, wherein the component elements thereof are arranged so as to be compact thus occupyingminimum space and proper circulation of heated water is assured and also heated air for the warming of an enclosure or enclosures, the apparatus being automatic in the working thereof.

A further object of the invention is the provision of an apparatus of this character, wherein the'construction thereof requires minimum attention in that the same is automatic in the working thereof and minimum consumption of fuel is required with resultant maximum heating eii'ect.

A still further object. of the invention is the provision ofl an apparatus of this character, which is comparatively simple in its construction, thoroughly reliable and eflicient in operation, and inexpensive to manufacture and install.

With these .and other objects in view, the invention consists in the features of construction, combination and arrangement of parts as will be hereinafter more fully described,v illustrated in the accompanying drawings, which disclose the preferred embodiment of the invention and pointed out in the claims hereunto appended.

In the accompanying drawings:

l Figure 3 is a sectional view taken vertically through Figure 2.. f

Figure 4 is a sectional view taken horizontally through Figure 2. y

Figure 5 is a fragmentary top plan view of the structure shown in Figure 2.

Similar reference characters indicate corresponding parts throughout the several views in the drawings.

Referring to the drawings in detail, A desigconduits I2 while a return conduit I3 is in asf sociation with the said rooms. The communicative points of theconduits I2 and I3 with the rooms B. are equipped with registers, generally indicated at Il. These conduits I2 and I3 are a part of a casing I5 in which is located a water radiator I6 of the tube type.

Within the furnace A above its firebox (not shown) is a pipe coil I1 having the end I8 opening into the top portion of a pressure water tank I9 while the other end 20 of this coil opens into the said tank I9 adjacent .the bottom, the tank being vertically disposed and supported in any suitable manner. 'I'he upper portion of the said tank I9 effects a steam dome 2|, the steam being generated by the coil Il in the working of the furnace A. This steam dome has common thereto a steam pressure gauge 22, release valve 22', water glass 23' 'and oil cup 24. Water is admitted to the tank I-9 from a water supply pipe 23 which opens into the large hot water tank 56 and communicates therefrom with the tank I9 through pipes 51 and 58 and its point of communication has associated therewith a float-operated cut-off valve 24. The pipe 23 is provided with a hand-operated cut-off valve 25. Hot water for domestic use is drawn from the hot water tank. 56 through pipe 64 where it is discharged through the faucet 65.

Leading from the water jacket IIl of the furnace A is a water pipe 26 which opens into the radiator I6 and interposed intermediate thereof is a manually-operated cut-off valve 26'. nected to the pipe 26 between the valve 26' and the water jacket I0 is a water pipe 59 which communicates at its other end with the hot water tank 56 adjacent its top. The pipe 51 leads from the lower portion of the tank 56 to the bottom portion of the heating jacket I Il to effect circulation of hot water between the tank 56 and the heating jacket I0. Projecting from the radiator I6 and provided with the cut-off valve 62 is a water disposal piper 63 for use when my invention is to be used as a cooling unit.

Arranged on a suitable support or stand 21 is a gear housing 28 which has built therewith at one side a steam cylinder 29 in which is reciprocatingly mounted a piston 30, its stem 3| being Con- - 1,: I slidable in a bearing 32 on the housing 28. This cylinder is built witha steam chest 33 in which works aslide valve, (not shown) for regulating the exhaust andfsupply of steam alternately at opposite sides' gf the piston 38 within and from the cylinder29; Steam from lthe dome 2| is delivered or admitted to the steam chest 33 by a lead pipe 34, the exhaust from the said chest being eii'ected in any desirable manner.

Bracketed above the housing 28 is the driving shaft 35 of a draft fan 36, which is of the bladed type. This drive shaft 35 is equipped with a belt pulley 31 having trained thereover an endless belt 38 which is also trained over a belt pulley 39 fixed to a driven shaft 48 journaled transversely in the housing 28. The fan 36 is within the casing I and is in confronting relation to the radiator I6 at the entrance of the returnconduit I3 to the said casing I5. Thus the spent heated air returned through the conduit I3 is blasted through the radiator \|6 for the reheating of this air and the transfer thereof through conduits I2 into the rooms B where such air will circulate and again return through conduit I3. The radiator I6 heats the air and such heating is continuous in the circulation of air through the system.

The driven shaft 48 has thereon a pinion 4I meshing with a gear'42, which is in association with a gear 43. The gear 43 meshes with gears 44 and 45, respectively, these being loose on a shaft 46 common thereto and such gears 44 and 45 are at opposite sides of the gear 43. Shiftable on the shaft 46 is a double' clutch'41 for alternately engaging the said gears 44 and 45, the clutch 41 being splined to the said shaft 46 for sliding movement. The shaft 46lhas fixed thereto a rack gear 48 meshing with a toothed rack 49 formed on the stem 3I of the piston 38.

The control 58 for the valve (not shown) within the steam chest, which is of any conventional form and is synchronized properly for the Working of said valve, actuates a bell crank lever 5I, which has connection with the clutch 41, so that on reciprocation of the stem 3| of the piston 38 in the working of the steam engine the said clutch 41 will be alternately clutched with the gears 44 and`45 thereby effecting a continuous drive in one direction to'the shaft 48 during reciprocation of the piston 38 within the cylinder 29.

The shaft 48 operates a rotary Water pump 52 which has the lead pipe 53 to the radiator I6 and the lead pipe 54 to the pipe 51. The pipe 51 conjoins the pipe 54 with the water jacket I8, and in this manner water circulation is assured through the radiator I6 in the Water iiow system of the apparatus. The pipe 54 is provided with a cut-off valve 54' and intermediate the water pump 52 and the cut-off valve 54 is connected a cooling unit pipe 68 which connects at its other end to the water supply pipe 23. The

' pipe 68 is provided with a cut-off valve 6I.

The gears 4I, 42, 44, 45 and clutch 41 are confined within the housing 28, the shafts 48 and 46 being suitably journaled therein. The pump 52 is suitably bracketed at 55 to the housing 2s at one side thereof preferably beneath the cyl'- inder 29 having the reciprocatory piston 38 therein.

When my invention is used as a heating unit, water is introduced into the unit fromthe supply pipe 23 and into the water jacket of the furnace A where it is heated. Water is also introduced into the pressure water tank I9 and heated in the coil I1. The steam within the steam dome 2| of the tank I9 enters the steam chest 33 through the pipe 34 vto actuate the piston 38 which, in turn, operates the fan actuating mechanism mounted within the housing 28, in the manner hereinbefore described. The steam'may be exhausted from the steam chest 33 in any suitable manner. Water is drawn from the water jacket I8 ofthe furnace and circulated through the pipe 26, radiator I6 and pipe 53 to the pump 52 and, from thel pump, the Water is forced back into thegwater.V jacket I8 through the pipes 54 and 51 t^ be reheated. Valves IiI and 62 in pipes 68 and 63, respectively, are closed and valves 26' and 54 in pipes 26 and 54, respectively, are

opened permitting the hot water from the Water y jacket I8 to circulate through the radiator I6l where the fan 36 blasts the spent air from the return conduit I3 through the radiator where it is reheated and forced back into the rooms B through conduits I2.

When my invention is to be used as a cooling unit, valves 26 and 54' in the pipes 26 and 54, respectively, are closed and valves 6I and 62 in pipes 68 and 63, respectively, are opened permitting the cool water from the supplyv pipe 23 to pass through the pipe 68, through the pump 52, and into the radiator I6 where it is discharged through the pipe 63, 'the fan 36 will then blast the spent air entering through the conduit I3 through the radiator I6 and the cooled air issuing therefrom will be forced into the rooms B through the conduits I2. 'I'he pump 52 is operated in themanner hereinbefore described, and the hot water for domestic use is heated in the-water jacket I8 of the furnace and obtained `from the hot water supply tank 56.

It is to be understood that the form of my invention, herewith shown and described, is to be taken as a preferred example ofthe same, and that various changes in the size, shape and arrangement of parts may be resorted to without departing from the spirit of my invention or the scope of the appended claims.
